There is a reason Hanoians often speak of October with a little nostalgia. The summer heat begins to fade, the air feels softer, and the city slowly moves into its most charming autumn rhythm. For travelers, this is one of the best times to enjoy Hanoi on foot, from quiet lake mornings and tree-lined streets to seasonal snacks, street food evenings, and easy day trips around Northern Vietnam. Still, October is not completely dry. Short showers, occasional storms, and weather changes can still happen, especially if your trip includes Halong Bay, Sapa, or mountain areas. This guide explains what Hanoi is really like in October, what to wear, what to do, and how to plan your days without worrying too much about the weather.

November is usually not a rainy month in Hanoi. Rainfall is much lower than in the summer and early autumn months, and heavy downpours are less common. That said, short showers can still happen. A day may start bright, become cloudy in the afternoon, and bring a light shower before clearing again. These weather changes rarely ruin a city trip if your schedule stays flexible. A compact umbrella or light rain jacket is enough for most November days in Hanoi. Comfortable walking shoes are also important, especially if pavements become damp after a short shower.

Since 2026, Vietnam has introduced a new online entry form for foreign travelers arriving by air: the Vietnam Pre-Arrival form. This free digital arrival card, also known as the Pre-Arrival Information form or PAI declaration, generates a QR code that may be checked by immigration officers when you land. In this guide, you’ll find out who needs to complete the form, which airports it applies to, when to submit it and how to fill it out step by step, so you can arrive in Vietnam prepared and avoid last-minute stress.

A stopover in Vietnam can be a great chance to discover Hanoi, Ho Chi Minh City or Da Nang for a few hours before your next flight. But before leaving the airport, you need to check three things first: your entry requirements, your baggage arrangement and whether your layover is long enough. Some Vietnam stopovers are very simple: you stay in the international transit area, your baggage is checked through, and you wait for your next flight. Others require more planning, especially if you have separate tickets, need to collect checked luggage, take a domestic flight in Vietnam or want to visit the city. This guide explains the most common Vietnam stopover situations, from visa rules and airport procedures to realistic short itineraries.

Lang Son isn’t always a must-see destination on a first short trip to Vietnam, but it can be a rewarding option if you want to venture off the beaten path. Set in the mountains of Northeast Vietnam near the Chinese border, the province offers limestone caves, local markets, cool mountain scenery, borderland culture and distinctive regional food. In this guide, discover the best things to do in Lang Son, from city caves and local markets to Mau Son Mountain, Bac Son Valley and borderland sites near Dong Dang. We also share when to visit, how to get there from Hanoi and how to decide whether Lang Son fits your northern Vietnam itinerary.

Vietnam’s hot season can feel intense, especially if you are not used to tropical humidity. The challenge is not only the temperature. It is the heavy air, the strong midday sun, sudden showers and short walks that feel longer than they look on the map. This is where many travelers misjudge the season. They prepare for “hot weather”, but not for how the heat changes the rhythm of a travel day. In our experience, Vietnam is not usually “too hot” for travel. The real problem is planning the day as if the heat were not there. This guide explains when Vietnam feels hottest, why the heat can feel stronger than expected, how to plan your days, what to wear, what to pack and where to go for a more comfortable summer itinerary.
